AgileEngine-Madison Reed|Remote - Villavicencio/Colombia

Redesigned the Madison Reed hair care brand e-commerce storefront, which supports ~500k monthly visits, working within a 4–6 person frontend team alongside QA and UI/UX. Implemented component architecture, SEO/AEO optimization, and performance improvements across 18–25 CMS templates, work the client described as record speed delivery.

Activities and Responsibilities

• Developed a reusable Vue.js 3 component library with Pug + Stylus, enforcing ADA/WCAG compliance, Core Web Vitals, and SEO/AEO optimization across Vue Router CMS templates, implementing JSON-LD injection and SSR integration.
• Optimized backend Node.js + Express.js + REST API performance through MySQL query refinement, connection pooling, rate limiting, and cache strategies, alongside Vuex/Pinia state management, plus Vite + Webpack code splitting, lazy loading, and prefetching for faster navigation.
• Ensured delivery and quality workflows covering BAs' ACs from Jira tickets and Figma UI/UX designs by using Vitest TDD unit testing, ESLint rules, Storybook documentation, Playwright E2E testing, and PR reviews.
• Created AI assisted validation workflows with Claude Code, Gemini, and Grok LLMs to automate ADA/WCAG compliance, Playwright E2E executions, and Sentry audits pre QA, avoiding regressions, with custom MCP tools and prompt chains for CI/CD and CMS velocity.

Key Impact

• Lifted Lighthouse performance from 45 to 68 and resolved 30+ accessibility violations, reducing page navigation from multi second delays to under 100ms.
• Raised Lighthouse SEO from 25 to 98 (100 on priority pages), grew new users from 5k to 8k monthly, and lifted conversion on redesigned flows from 20% to 38% with the landing-to-booking funnel climbing from 6% to 18%.
• Shipped features at 2–3× previous velocity, reducing ticket cycle time from 3–4 days to 1–2 days and cutting QA rounds from 4–6 to 1–2, a pace the client called record speed.
